After making a dramatic gesture and uttering a few words of power, you close your eyes and open them again, revealing all that is hidden.
All creatures and objects within a zone of revelation are made visible. This includes invisible creatures, as well as those on coexistent planes such as the Ethereal Plane and the Plane of Shadow. Natives of these planes do not lose any abilities but are simply made visible.
Zone of revelation suppresses but does not dispel invisibility, etherealness, or other spells. Once a formerly invisible object or creature leaves the area, it becomes invisible again. Ethereal creatures in the spell’s area become nonethereal until they move beyond the spell’s range.
Arcane Material Component: A handful of dust from the grave clothes of an undead creature.
